#14597: Consider removing uses of unsafeGlobalDynFlags for -dppr-debug -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Currently various functions in `Outputable` use `unsafeGlobalDynFlags` to get the state of `-dppr-debug`. `unsafeGlobalDynFlags` is rather ugly, being a blob of global state spanning both module compilations and GHC API sessions. Consequently, we might consider removing it. On the other hand, `-dppr-debug` is strictly a debug flag and removing `unsafeGlobalDynFlags` would likely require a lot more piping around of `DynFlags`. Consequently I suspect our current compromise of using `unsafeGlobalDynFlags` is the right solution. Nevertheless, I thought I would jot down the task. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14597 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
